I have a data bound grid. I use GridModelCutPaste.Paste to paste a row I just copied. I set EnableAddNew to true. If I try to paste to the last row (the fake one used to add record), I get an exception. If I paste to a real row, it works fine. Here''s the stack trace: Object reference not set to an instance of an object. at Syncfusion.Windows.Forms.Grid.GridModelDataBinder.SaveCellInfo(GridSaveCellInfoEventArgs e) at Syncfusion.Windows.Forms.Grid.GridModelDataBinder.Syncfusion.Windows.Forms.Grid.IGridModelDataProvider.SaveCellInfo(GridSaveCellInfoEventArgs e) at Syncfusion.Windows.Forms.Grid.GridModel.SetCellInfo(Int32 rowIndex, Int32 colIndex, GridStyleInfo style, StyleModifyType modifyType, Boolean dontRaiseSaveCellInfoEvent, Boolean copyReferenceOnly) at Syncfusion.Windows.Forms.Grid.GridModel.SetCellInfo(Int32 rowIndex, Int32 colIndex, GridStyleInfo style, StyleModifyType modifyType) at Syncfusion.Windows.Forms.Grid.GridModel.ChangeCells(GridRangeInfo range, GridStyleInfo[] cellsInfo, StyleModifyType modifyType) at Syncfusion.Windows.Forms.Grid.GridModel.Syncfusion.Windows.Forms.Grid.IGridVolatileDataContainer.ChangeCell(Int32 rowIndex, Int32 colIndex, GridStyleInfo style) at Syncfusion.Windows.Forms.Grid.GridVolatileData.set_Item(Int32 rowIndex, Int32 colIndex, GridStyleInfo value) at Syncfusion.Windows.Forms.Grid.GridStyleInfoIdentity.OnStyleChanged(StyleInfoBase style, StyleInfoProperty sip) at Syncfusion.Styles.StyleInfoBase.OnStyleChanged(StyleInfoProperty sip) at Syncfusion.Windows.Forms.Grid.GridStyleInfo.OnStyleChanged(StyleInfoProperty sip) at Syncfusion.Styles.StyleInfoBase.SetValue(StyleInfoProperty sip, Object value) at Syncfusion.Windows.Forms.Grid.GridStyleInfo.set_CellValue(Object value) at Syncfusion.Windows.Forms.Grid.GridCellModelBase.ApplyFormattedText(GridStyleInfo style, String text, Int32 textInfo) at Syncfusion.Windows.Forms.Grid.GridComboBoxCellModel.ApplyFormattedText(GridStyleInfo style, String text, Int32 textInfo) at Syncfusion.Windows.Forms.Grid.GridStyleInfo.ApplyFormattedText(String text, Int32 textInfo) at Syncfusion.Windows.Forms.Grid.GridModelTextDataExchange.PasteTextRowCol(Int32 rowIndex, Int32 colIndex, String text) at Syncfusion.Windows.Forms.Grid.GridModelDataBinder.DataBoundPaste(IDataObject iData, Int32 clipboardFlags, GridRangeInfoList rangeList, GridCutPasteEventArgs e) at Syncfusion.Windows.Forms.Grid.GridDataBoundGridModel.OnClipboardPaste(GridCutPasteEventArgs e) at Syncfusion.Windows.Forms.Grid.GridModel.RaiseClipboardPaste(GridCutPasteEventArgs e) at Syncfusion.Windows.Forms.Grid.GridModelCutPaste.Paste() at SDB.viewRule.HandleCommand(String cmd, Object arg) at SDB.cmdDispatcher.DispatchCommand(String cmd, Object arg)

If you want to append rows dusing a paste, you will have to handle this your self. One way is to subscribe to the PasteCellText and add the row there is needed.
//subscribe to the event
this.gridDataBoundGrid1.Model.PasteCellText += new GridPasteCellTextEventHandler(Model_PasteCellText);

//the handler
private void Model_PasteCellText(object sender, GridPasteCellTextEventArgs e)
	if(e.ColIndex > this.gridDataBoundGrid1.Model.ColCount)
		e.Cancel = true;
	else if(e.RowIndex == this.gridDataBoundGrid1.Model.RowCount)
		CurrencyManager cm = this.gridDataBoundGrid1.BindingContext[this.gridDataBoundGrid1.DataSource, 
			                                    this.gridDataBoundGrid1.DataMember] as CurrencyManager;
	else if(e.RowIndex >= this.gridDataBoundGrid1.Model.RowCount)
		e.Cancel = true;
